Neo4j 1.9.M03 released

in the middle of the end-of-year festivities we are happy to announce another Neo4j 1.9 milestone before the year ends. This time, it is a milestone that is all about stability for 1.9.GA and paves the way for a major dependency version upgrade in the next version. For a full changelog, see the original on Github.

Kernel

We removed an issue with relationship-type-id’s which allows everyone to use the full size of 16 bit aka 65535 different relationship-types now. We also worked on the Java7/OpenJDK support (so far compilation and tests).

High Availability

For the new HA mode we improved the logging, added more tests and made it more robust on startup and when clients leave the cluster in order to stabilize the component for Neo4j 1.9.GA.

Server

In this milestone, the code for the Tinkerpop integration into the Neo4j Server and its Web-Interface and the Gremlin Plugin has been refactored and centralized. This makes all Tinkerpop dependencies reside only inside that plugin. So it will be possible to support two versions of the Gremlin plugin, one for the 1.5 release and another plugin for the current 2.2.

Cypher

Cypher got a lot of internal refactoring, especially around the internal handling of start- and updating clauses and general parse-result representation and management.
